[Umbrella-Item] Make WinForms DataBinding Apps trimmable

[KlausLoeffelmann]

This is an investigation and prototype issue at this point (with some good prospects of success, though).

• [ ] Investigate options to improve Designer-side code generation to support Trimming for WinForms App which use Designer-hooked-up Data Binding (we will explicitly exclude non-type-safe Data Binding, like Runtime-Binding to DataTables/DataViews which use Property Descriptors to create "Types" at runtime.)

• [ ] Investigate schema-discovery based on custom type descriptors, and runtime type conversions via reflection and the impact on trimming. Also take

  • [ ] the Binding.Format event
  • [ ] the Binding.Parse event
  • [ ] the different intrinsic ways to convert to target on binding
  • [ ] the different intrinsic ways to convert to source on binding
  • [ ] Maybe schema-generation in the DataGridView, like described in this request/API suggestion

  into account.

• [ ] Investigate runtime API-Improvements around
  • [ ] Binding
  • [ ] BindingSource
  • [ ] Formatter
  • [ ] ListBindingHelper
  • [ ] ListBindingConverter
  • [ ] BindingList

I'm super excited to see how this goes!
